Subject [jira] [Updated] (AMQCPP-449) activemq::library::ActiveMQCPP::shutdownLibrary(); causing runtime exception
Date Wed, 16 Jan 2013 20:16:13 GMT


Timothy Bish updated AMQCPP-449:

    Attachment: amqdriver.cpp

Updated your app and placed the AMQCPP Object in their own scope so that the Thread object
producerThread goes out of scope and is destroyed prior to the shutdownLibrary call, that
should address your issue.

>                 URL:
>             Project: ActiveMQ C++ Client
>          Issue Type: Bug
>          Components: Decaf
>    Affects Versions: 3.5.0
>         Environment: HPUX 11.31
>            Reporter: Jeffrey B
>            Assignee: Timothy Bish
>            Priority: Critical

>         Attachments: amqdriver.cpp, amqdriver.cpp
> Whenever my simple driver application or my receiver application call the shutdownLibrary()
method at the end, as the program is going through desctuctors for threads it prints and causes
a core dump
> aCC runtime: Unexpected exception of type "decaf::lang::exceptions::RuntimeException".

> aCC runtime: what(): Failed to Lock OS Mutex 
> Abort(coredump) 
> I added another catch and print in decaf/lang/Thread.cpp about line 133 and on decaf/internal/util/concurrent/unix/PlatformThread.cpp
about line 76 i printed out ther error number return from pthread_mutex_lock()
> Now i get:
> Failed to Lock OS Mutex, Error num: 22
>         FILE: decaf/internal/util/concurrent/unix/PlatformThread.cpp, LINE: 78
> aCC runtime: Unexpected exception of type "decaf::lang::exceptions::RuntimeException".
> aCC runtime: what(): Failed to Lock OS Mutex, Error num: 22
> Abort(coredump)
> Error 22 is EINVAL and can have two meanings on my system:
>      mutex is a PTHREAD_PRIO_PROTECT mutex and the caller's priority is higher than mutex's
priority ceiling.
>      mutex is not an initialized mutex.
> I'll try and upload my code to see if this happens on other systems as well.
